If you want to make a startup but don't because there is a similar product or "every niche is already occupied", quit thinking this way.

Yahoo could once easily buy Google. They even received the offer but rejected it. But as for now, Yahoo is nothing.

Tumblr was once a top social network, but they crumbled. Foursquare once was preinstalled to smartphones, and now it pretty much doesn't exist.

Blackberry was a giant, the number one smartphone manufacturer. Where are they now? It wasn't betrayal like it was with Nokia and Stephen Elop.

Matter of fact, I'm now working for the company that entered a heavily occupied niche and over the course of three years pushed every competitor out.

Sometimes giants crumble. Small products crumble way more often, just because there are more of them.

There is always enough room in every niche of every industry. Just enough for your startup. Now, as you can't hide under "it's already occupied, and I can do nothing about it" mindset, the only reason your startup won't make it is that you don't work on it. Yes, accepting it is way less comfortable than hiding, but now you're able to change things. You _can_ do something about it.

Evaluate your goals, ask yourself whether making this startup would be just wasted time in case it never takes off, and if you think it's still worth doing, do it.

There is always enough room for your masterpiece.
